Nice pics Steve.
I just use the channels that the data ends up in so I bin 1x1. Usually I keep red for Ha and Sii, Green and blue for Oiii. I stack all the HaRed, SiiRed, OiiiBlue and OiiiGreen separately and do a data rejection. Then I stack the Oiii Green and Blue into one Oiii. All the rest is noise so I don't use it at all.
I haven't tried binning but I assume that if you bin 2x2 you'd collect all this noise together in one monochrome picture that has half the resolution.
